antagonists · Lear’s daughters Goneril and Regan; Edmund, the bastard
son of Gloucester

setting (time) · Eighth century b.c.

setting (place) · Various locations in England

later cruel treatment of Lear.

tone · Serious and tragic; the occasional bursts of comedy
are uniformly dark

themes · Justice, authority versus chaos, reconciliation, redemption

motifs · Madness, betrayal, death

symbols · Weather plays an important symbolic role in the play,
notably in Act 3, when the tremendous thunderstorm over the heath symbolizes
Lear’s rage and mounting insanity; the actual blindness of Gloucester
symbolizes the moral blindness that plagues both Lear and Gloucester
himself in their dealings with their children; the “wheel” of fortune
is another symbol by means of which Edmund, at the end of the play,
conceives of his fall from power back into insignificance.

it is kind of confusing dealing with King Lear and his three daughters, and then having to deal with Gloucester. My suggestion, think of the movie Thor:

-Gloucester: Odin-son
-Edgar: Thor (the good brother who is supposed to succeed Odin-son/Gloucester when he dies; is deceived by Loki/Edmund and then gets punished)
-Edmund: Loki (the evil, illegitimate brother who is jealous of Thor/Edgar (except Loki was adopted); gets control of the throne for a while)
